Patent number: 8647339Abstract: It is an object of the present invention to provide a radiofrequency thermal balloon catheter system capable of precisely predicting the surface temperature of a balloon which directly heats a target tissue without allowing a temperature sensor to directly contact with a balloon membrane. In the radiofrequency thermal balloon catheter system, a vibrational wave W is applied to an inside of the balloon 6 through a solution transport path 11 by means of a vibration generator 42. An in-balloon temperature sensor 8 is insulated from the electrode 7 for delivery of radiofrequency current to be fixed in the vicinity of a distal end of an inner tube 3 and then the temperature of the swirls S flowing along the inner surface of the balloon 6 is detected.Type: GrantFiled: December 19, 2008Date of Patent: February 11, 2014Assignee: Japan Electel Inc.Inventor: Shutaro Satake

Patent number: 8641711Abstract: Devices and methods for ablating tissue in the wall of various organs of the gastrointestinal tract of a patient in order to cure or ameliorate metabolic pathophysiological conditions such as obesity, insulin resistance, or type 2 diabetes mellitus are provided. Ablational treatment of target areas may be fractional or partial, rendering a post-treatment portion of target tissue ablated and another portion that is substantially intact. Fractional ablation is achieved by controlling the delivery of ablational energy across the surface area being treated, and controlling the depth of energy penetration into tissue. Surface area control of energy delivery may controlled by the spatial pattern of distributed ablation elements or by the selective activation of a subset of a dense pattern of ablation elements. Embodiments of the device include an ablational electrode array that spans 360 degrees and an array that spans an arc of less than 360 degrees.Type: GrantFiled: May 2, 2008Date of Patent: February 4, 2014Assignee: Covidien LPInventors: Douglas Kelly, David S.

Patent number: 8613742Abstract: A method for sealing fluid-carrying vessels in a living organism using high temperature plasma is disclosed. A flow rate of 0.25-0.5 L/min of room-temperature plasma generating gas and the initial temperature of the discharged plasma of 12.5-15.5 kK ensure a laminar plasma flow and its ability to penetrate into the vessel. The plasma flow is directed into the vessel, where it keeps a portion of the vessel free of liquid. Heat is transferred to the vessel walls, and the denaturing of collagen in the vessel walls causes the walls to contract until complete occlusion occurs. The method may be used with devices adapted for tissue dissection and coagulation.Type: GrantFiled: January 29, 2010Date of Patent: December 24, 2013Assignee: Plasma Surgical Investments LimitedInventor: Nikolay Suslov

Patent number: 8574227Abstract: A surgical antenna for radiating microwave energy (e.g. frequency 500 MHz to 60 GHz) from a e.g. ceramic insertion tip (60) into biological tissue is disclosed. The tip is provided at the end of an elongate body which delivers the microwave energy to the tip via an inner conductor (30), an outer conductor (20) surrounding the inner conductor and a dielectric material (50) therebetween. The impedance of the insertion tip (60) is selected to improve impedance matching with the complex conjugate of the complex impedance of the tissue at a treatment frequency. For example the insertion tip may act as or include at least one quarter wavelength impedance transformer. By closely matching the antenna's impedance to the tissue, dynamic tuning (if used) can be performed much more efficiently. Impedance matching at the tip can also focus the radiated energy distribution.Type: GrantFiled: October 9, 2007Date of Patent: November 5, 2013Assignee: Medical Device Innovations LimitedInventors: Christopher Paul Hancock, Malcolm White
